In Digimon Card game, Purple is the color that makes player heavily uses their brain when building the deck or playing (except for Rookie Rush deck). Bandai even rates purple as the most strategic color. Purple deck pace is very slow, so player needs to be carefully building a deck with a proper strategy in order to win the game. The BT04 Great Legend came last month, pushing the Green and Yellow power to its PEAK, especially Green. Purple haven't reached its time yet and still waiting for a better support from BT5 onward.
Playing digimon card game with a purple deck do really bring me headache, the game lasts very long, there is too many cards in hands, there is too many option to choose, you have to draw then trash… But it is really fun.
